Be it -lmown that I, SPENCER Oris, a citi zen of the United States, residing at Chicago, in the `Vcounty of Cook and Slate of Illinois, have invented certain new and useful. Im-

provements in Cars, of which the following' v 'of the car.

car.

The principal` object of the invention isto provide a simple, economical and eflicient A further object is to provide. a carhaving longitudinal center sillsy with intermediate sills suitably ftrussed and having needle beams supported by such intermediate sills and extending underthe center sills ada ted to transfer a portion 'of the Weight ofthe load from the oenters'ills to the trussed intermediate sills, and all so connected as to form an golellicient longitudinal trussed beam mechanism forming the main supporting framework for the car.

IA 'further object is to provide an efficiently trussed longitudinal beam mechanism so constructed and arranged f upon suitable holsters las to be adapted to carry the WeightV of the load, and provide ample space at each mechanism mounted in suitable holsters and side of such longitudinal beam mechanism to permit the dumping of the load between such 4o ongitudinalkbeam mechanism and the side frames'. y

Other and hnther objects of the invention will appear from an examination of the drawings andthe following description and claims,

The invention consists in a supporting framework having longitudinal center sill trussed longitudinalv sills on opposite sides thereofprovided with needle beams supported by the trussed sills and extending beneath the center sill mechanism, adapted to transfer a portion of the Weight ofthe load from the longitudinal center sill mechanism to l vsuch trussed sills, and all forming the main su 'porting framework of the car. .It consists further, and finally, in the features, combinations and details of construction hereinafter described and claimed. i In the accompanying drawings-Figure l is an end elevation of a car constructed in ac cordance with my improvements Fi 2 a side elevation of one end of the car; Flg. 3 a

central sectional elevation of the opposite' end of the car not shown in Fig. 2; Fig. 4 a transverse sectional elevation, taken online e oi Fig. 3, looking in the direction of the arrow; and Fig. 5 a plan view' o'f the supporting framework ofthe portion of the car shown 1n Fig. 3 with the lined and swinging or dump ing door sections removed.

n constructing a car in 'accordance withv provide a supporting my improvements, I framework having a pair of longitudinal cen- .ter sills orI formed of channel irons arranged With their upper and lower flanges extending outward laterally. Intermediate longitudinal sills here mountedon fa lane slightly below the level ofthe center sill sand formed ofchannel irons having their lateral top and Ibottom Yilanges extending inward toward the lonvitudinal center of the car. lon itudinal sills 'extend irom end sill to end sill hrough suitable openings c, d, e and f in bodybolsters g, which are sup orted in anyi ordinary manner upon trucks L, which may be of any ordinary and Well known type.

`Each ofthe intermediate sills above de-v scribed is provided with a truss member 'i These which is oblong in cross section and' has its greatest Width in'a vertical plane. These truss members `extend longitudinally of the car below the lntermediate sills, and at each end thereof they extend upward and longi tudinally ot' the car at an incline having their opposite end portions extending through the openings c and j', respectively, in the bodv n holsters and secured tothe intermediate sills ab t. ivetS. t Struts for the longitudinal trusses Aare formed of vertical center pieces 21 and angle iron side members 22 and 23, having their yond 'suchbody holsters 'by meanest suit laterallyprojecting anges secured to auch center pieces by means of rivets, es shown in .Flg 2. Then iron side mem ers extend upward and 'longiper end portions of such angle gros' lower chords of the trusses by means of.

rivets 25. Mounted between the trusses opposite these strut members and independently thereof are transverse needle beams y', which have their opposite' ends secured to. the inner sides of the lower chords of the trusses above describediby means o angle ironslc. These needle beams extend transveisely beneath and supportfthef longitudinal center' sills, so as to transfer aportion ofthe Weight of the load from suclr center sills to the trussedside or intermediate sills which snp ort the needle-beams. The upper'edges of t ese needle beams are provided-with an-` Ie irons l forming' lateral strengthening anges adapted to beseour'ed to the center sills, desired, and the trussed sillsmay be securedto the bolstersby means of rivets 26, a' .plate v27 beingalso mounted upon and se'- cured` to the longitudinal sills adjacent to each bolster'. Transverse" -eams m are provided, forined'of, side members Sil-having a central v web portion 31 therebetween and each having a- T-shaed'ltop member 32, the depending centra/l' an e of which extends between 'thefsidemem "ers of such beams, being secured 'thereto by means of rivets, the

i laterall Rangesextending` outward laterally beyondtlle sidesof' suchl beams,v These.

transverse metallic beams are mounted upon and supported-by thelongitudinal sills at suitable "interyafl's to permit 'the swinging of the" dump' gdo's' therebetween, as hereinafter described. y

A superstructure is' provide' side frames n, end'dran'ies o, swii ing' dum ing bottom se'etionsp and a central lix'ed oor section g. LThe'sv'inginlg dumping botto'm sections arepivotally secured to the'frame` work of the car-by means el' shafts 1^, which extend longitudinally from end to endof the earA near the center thereof, The swinging dumping bottom sections are operated b'y means of'hand wheels ljupon operatinglshafts t, having worms engagement with-Worm wheels o uponthe door supporting and operi-A ating shafts. Shafts w extend longitudinally of the car' beneath the doors and arev reciprocatin ly mounted upon upwardl and outwar y inclined trac' connected to the door supporti means of cranks 2 and pivote arms 8. The rotation of the hand Wheels in one direction will,`therefore, -move the shafts 'w toward the center of the car to loweredposition, permitting the doors to dropjto open inclined dumping osition, and the' rotation of the o erating w eelsin the opposite direc'- tion wil raise'the doors and move the shafts shartslr by s y, such s ais being' connecting.

ptingthe longitudinal center sills, 'and bo y w into "position to support the outer edges ol the door, as shown in Fig. 4.

-Suitable end sills are provided, the main body portions of which are loi-med ofv channel lrons 5 havingl bottom flanges 6 and top flanges 7 extending outward laterally 'from the vertical web portions of such channel irons endwise of the car, and a to plate 8 is secured to the upper sides of the c annel iron members of such end sills and also secured to the' end board of the car vby means of an angle iron 9. These end sills are secured to intermediate longitudinal sills bv means of AgussetIl plates 28v and to the center sills by means, of angle plates 29. .Dead blocks 10, which may be of any ordinary and well `known construction, are mounted upon the outside of the channel iron members of the end sills between the upper and lower flanges thereof, and suoli channel iron members are each rovided with a central vnotch 11 throng 'which the draw-bar shank extends.

Aearrierarm 12, formed of an angle iron with its horizontal flange 13 extending outward from its up er edge, is secured to the channel iron mem er of each end sill, so as to extend across the lower side of the opening or notch, such carrier arm being secured to the channel iron member by means of-bolts or rivets 14, so as to support the draw-bar shank l15. `A supporting arm 16 also extends across the -lower edge of the notch and is v secured by means of rivets 17 to the lower ilange'oi each channel iron member.

The' end frames, and side frames of the car are termed of planks and the corners are IOO strengthened by means of angle ironlcorner plates 18. The side frames are provided with metallic side stakes 19 mounted on the inner sides thereof over the transverse beams and haring lateral flanges securedto the side boards, the transverse web portionsof such f side stakes extending downward atan incline and being secured at their bottom ends to the transverse by means' of angle l longitudinal center sills, trussed longitudinal sills mounted upon opposite sides thereof, transverse needle beams supported by such truss'ed'sills and extending beneath and su plsters upon which such longitudinal sil mechanism is supported.
